Marine Diesel Tank Repair

[@vincetreverton3297]

John, that is undoubtedly a good way to fix a specific leak, but in my case, I wanted to prevent any further leaks as more pin holes could develop with time. Using the fibreglass should ensure no more leaks even if the seam rusts though again.

Had the same Problem on a president 55. They repaired it in a similar way, but welded it. Your solution seems much easier. I stored the KZbin for next time. (Hopefully not on my boat). Good Video!!

Ingenious repair. Is it still holding?

Your video was so helpful thank you. Is there a special you use use fiberglass resin or polyurethane with the fiberglass

Hi. This video is the first is what I hope will be a series documenting the repairs and improvements to my lovely 30-year old Dyna 53 Cruiser. Here, we repair an inaccessible leak from the port diesel tank by getting inside it to fix it. Dirty but Doable!! Next in the series will be the installation of a mini split air conditioner of the type used in a home to replace the noisy and inefficient marine air con unit in the front cabin. Also I will be installing an electric reverse osmosis water maker from components which will be powered by my diesel genes. This will allow autonomous operation and allow longer sea trips around the Hong Kong area where the boat lives. I hope the series will assist anyone thinking of doing the same projects. Have fun and be safe!

Researching tank repair similar deal , I have alum. Don’t think fiberglass will work but not sure on alum . What the verdict?

[@stevenbelland6677]

Oh my gosh, we have the exact same boat and have the same problem. Did this work and would you have done anything different?

Aluminum and steel together. Two dissimilar metals together, Big no no .

I'm just thinking aloud here, Don't shoot me, but what would happen if you used Rocol dye check, weld dye, and purged inside of diesel tank with Pure Argon gas, then Tig welded the pin holes, with the unlucky welder having a snorkel air feed to the outside and a rescue person incase he was short of breath? I think thats the way I would have done it on my Diesel tank. Just a thought? Im lucky I had only to repair stainless holding water tanks.

He had the inside of the tank cleaned out. In the video he said he was worried about the diesel that had leaked onto the beam below the tank catching fire if he welded 8.08. The beam had so much diesel on it that it wicked back in the tank 7.53.
